PARAGRAPHING-STOP FOR TYPE-WRITING MACHINES.

SPECIFICATION forming p of L r P en N 784,494, dated March 7, 1905.

Application filed October 21,1902. Serial No. 128,113.

To 111/ whom it may concern.-

Be it known that 1, CHARLES R. KELLY, of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Paragraphing-Stops for Type-VVriting Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in typewriting machines; and its object is to provide a simple and effective device whereby the op erator can arrest the return movement of the carriage at will at any desired predetermined point without having to be guided in so doing by the position of the pointer on the scale.

The device may be termed an improved paragraphing-stop, as it enables the operator to use the machine in the ordinary manner to write full lines at will or to paragraph or tabulate matter very rapidly. Various devices have been devised and patented for this purpose, and I do not claim to be the first to do this; but the devices heretofore made have generally been devices which would release the escapement and allow the platen-carriage to move rapidly to the left until arrested by a stop after the carriage had been moved to the right. The prior devices have always further required the operator to employ both hands when desiring to use the paragraphing-stop. The ,maj ority of these devices have only been applicable to some special kind or make of machines.

My present invention is applicable to practically any machine using a sliding carriage, and particularly to type-bar machines.

In my invention I place the paragraphing stop or device on the front of the machine and use it to arrest the movement of the carriage to the right. The stop may be operated by pressure of the thumb of the hand moving the carriage to the right simultaneously with the moving thereof. This is a matter of great convenience and practical use. My paragraphing-stop, moreover, automatically throws itself out of action as soon as the thumb-pressure is released, and if thecarriage is stopped thereby in paragraphing position the operator may by simply removing his thumb from the thumb-piece disengage the stop and move the carriage farther on to the right without having to manipulate any parts at all. The paragraplistop indicator may be conveniently attached to the usual front index-scale attached to the carriage of the machine, or, in other words, the front index-scale bar usually attached to the carriages of the Remington, Smith Premier, and like machines may be utilized as a part of my paragraphing-stop, and in practice I also utilize the fixed pointer ordinarily used on such machines as part of my paragraphing-stop.

The invention is summarized in the claims, and I have illustrated the invention in the drawings as applied to the Remington typewriter.

In said drawings, Figure 1 is a top plan view of a portion of a writing-machines, howing my improved paragraphing-stop applied thereto. Fig. 2 is a transverse section on line 2 2, Fig. 1, showing the paragraphing stop in normal or inoperative position. Fig. 3 is a similar view showing the paragraphingstop in operative position. Fig. 4 is a detailed rear view of the portion of the device attached to the carriage, and Fig. 5 is a detailed view of a portion of the paragraphingstop attached to the front carriage guide-bar. Fig. 6 is a detail perspective view of part of a type-writing machine, showing a modified construction of the invention. Fig. 7 is a detail section on line 7 7, Fig. 6.

The type-writer carriage a may be of ordinary construction, having a platen b, which can be rotated by means of the handle 0, pivoted to one end of the carriage and provided with means for rotating the platen, as customarily employed in such machines. These parts being well understood, a particular description thereof is unnecessary"; and they are simply conventionally illustrated in the drawings. I The machines are ordinarily provided with an index-scale attached to the front side thereof and moving past a relatively fixed pointer, as indicated in Figs. 1 to 4. My device, however, may be applied to a machine where the pointer 1s attached to the carriage point thereon.

and the scale affixed to the frame, as indicated in Fig. 6.

Instead of making the part attached to the carriage rigid I hinge it thereto. In the present instance the scale d instead of being rigidly connected to the carriage is hinged thereto by means of supports f, being hinged at their inner ends, as shown at g, to plates h, attached to the front bar of the carriage in any suitable way. A spring t is arranged to throw the scale (1 upward, so as to retain it normally in one certain position, the movement of the scale being limited by stops (1 (1, attached to its end and projecting, respectively, above and below the handle 0 adjacent to its pivot. The scale-bar d is utilized in my invention as part of the paragraphing device, and is therefore provided on one edge with serrations d which are adapted to be engaged by teeth j on a slide j, so as to lock the slide to the bar, a spring j being interposed between the opposite edge of the scale-bar and the slide, so as to normallylock the slide to the bar; but by depressing the slide so as to compress the spring the teeth j may be disengaged from the teeth (1 and the slide can then be slid to right or left on the bar, and thus set at any desired The slide is provided with a pointer j by which its position on the scalebar is determined, and the position of the slide on the bar will determine the point at which the paragraphing-stop will arrest return movement of the carriage. The slide is provided with an inwardly-projecting lug j, which is adapted to engage with an upstanding lug e on the pointer e, the lug e lying under the scalebar, while the point 6 projects in front thereof.

In its normal position the scale-bar is upheld by spring 'i and will not permit contact of the lugs j and e, and the carriage may be moved back and forth to the full extent of its travel. If, however, the scale-bar be depressed inward or downward prior to and during the return movement of the carriage,

the lug y'" will come in position to contact lug v e and when it strikes the latter will arrest the return movement of carriage at the desired paragraphing position. For instance, if the slide 9' be set at 20 on the scale the paragraphing-stop will arrest the return of the carriage at 20 when the scale-bar is depressed. The scale-bar may be depressed by the thumb of the operator when he grasps the handle 0, as indicated in the drawings. A thumb-piece d may be attached to the right-hand end of the scale-bar and project adjacent to the handle c in position to be very conveniently engaged and depressed by the thumb of the op erator, as indicated in Fig. 3.

The operation is as follows: The front scalebar in the illustration shown is normally held outward by the spring, and in this position the carriage may be drawn all the way from left to right without the paragraphing-stops contacting; but when the scale-bar is depressed by the thumb the adjustable stop is brought into position to strike the shoulder or lug e on the index-finger, which may be attached to a fixed part of the machine, or, on shifting-carriage type-writers, such as the Remington machine, may be placed on the shift-rod. When so depressed, the paragraphin'g-stops arrest the carriage at the point for which the slide is adjusted. When applied to shifting-platen machines, the paragraphing-stops maintain the same relative position whether the carriage is shifted for upper or lower case.

Inthe modified illustration in Fig. 6 scale D is fixed to the front bar of the frame of the machine, set out sufficiently therefrom to allow the slide to be adjusted thereon. The pointer E is attached to a rock-shaft E, journaled on the front bar of the carriage and having a thumb-piece E by which it can be depressed, so as to swing into position to engage a lug on the slide 7', as shown. A spring E may be arranged to swing the pointer normally outward out of position to engage the slide except when piece E is depressed. When i the thumb-piece is not depressed, the pointer will pass the slide without contacting it. The extent of swinging movement of pointer E can be regulated in any suitable way, and the edge of the pointer is preferably squared to contact with the lug on slide. This arrangement of parts is just the reverse of that shown in Figs. 2 and 3, as the pointer swings instead of the scale-bar. The teeth are on the upper edge of the scale-bar. The slide pushes up from bottom instead of down from the top, and the striking-lug is on top of the slide instead of on its bottom.

Various modifications might be made in the devices within the scope of my present invention, and I therefore do not wish to be restricted to the particular construction and application of the device herein shown and described.

It will be observed that after the paragraphing-stops have arrested the return movement of the carriage if the operator desires he can move the carriage farther on to the right by simply releasing the pressure on the scale-bar, whereupon the spring 0; instantly throws the scale-bar outward, so as to disengage the paragraphing-stop lugs. They are, moreover, thrown out of engaging position whenever the operator removes his hand from the carriage.

As the device requires but one hand to operate it, the copyist can throw the paragraphingstop into or out of position simultaneously with the moving of the carriage, it only being necessary that he depress the paragraphing-bar before the carriage on its return stroke has reached the paragraphingpoint.

Having thus described my invention,what

I therefore claim as new, and desire to secure by Letters Patent thereon, is

1. In a paragraphing-stop for type-writing machines, the combination of a front scale, an adjustable paragraphing-stop attached to the scale, a second coacting stop, the scale and coacting stop being respectively attached to the carriage and to a relative stationary fixed portion of the machine, s ringcontrolled means for holding one of said stops normally out of the path of the other stop, and means for depressing said stop into contacting position to arrest the return movement of the carriage.

2. The combination of a type-writer carriage, a swinging bar attached to the front thereof adjacent to the carriage-controlling lever in position to be depressed by the thumb of the operators hand grasping the carriagecontrolling lever, a paragraphingstop on said swinging bar and a coacting paragraphing-stop on a relatively fixed position of the machine, said stops being adapted to contact when the swinging bar is depressed and arrest the movement of the carriage at any predetermined point during its return movement to the right, substantially as described.

3. The combination in a type-writer, of a swinging bar attached to the front of the type-writer carriage, a sliding paragraphingstop attached to said bar, a relatively fixed paragraphing-stop attached to the machine, a thumb-piece on said swinging bar adjacent to the carriage-manipulating handle, whereby said bar may be depressed so as to bring the stop thereon in position to contact with the fixed stop by the thumb of the hand moving the carriage to the right.

4. In a type-writing machine, the combination of the platen, a laterally movable or swinging scale-bar attached to the front thereof, a spring for holding said scale-bar in forward or upward position, said scale-bar being adapted to be depressed or shifted by the thumb of the operators hand grasping the carriage-manipulating handle, a laterally-adjustable paragraphing-stop on said bar, and a fixed stop attached to an adjacent part of the machine adapted to contact with the stop on the scale when the latter is depressed and the carriage moved to the right, all substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix mysignature in presence of two witnesses.
